applloation filed December 16,1902. Serial No. 135,361.

To all whom it mayconcern:

Be it known that I, BURNHAM C. Snore Writing Machines, of which-the following is a specification.

This invention relates primarily to typewritin machines in which radially-disposed type are are arranged about a common printing-point and move one at a time to the printing position. These type-bars, espe cially in front-strike machines, are often closely arran ed, so that in rapid operation there is liabiity of clashing, due largely to the fact that the type-bars are apt to rebound from the basket or cushion upon returning to normal position, thus getting into the path of a subsequently-operated type-bar. I

The principal object of my invention, therefore, is to minimize the liability of the typebarato rebound in this manner.

. in the drawings forming part of this specifica'tion, and in which like signs denote like parts, Figure 1 is a sectional elevation of a type-bar, type-basket, and platen of an under-strike machine, and by turning the figure quarter-way around it will be seen that it represents like parts in a front-strike machine, in which the type-bars lie horizontally and below the lane of the printing-point.

Fig. 2 is a'plan o the type basket or ring seen at Fig. 1, the type-bars being indicated in cross-section. Fig. of the basket seen at Fig. 1.

Referring to Figs. 1 and 2, a radial series of type-bars 1, carrying types 2, which strike against a platen 3, is supported by hangers 4 upon a ring, segment, or plate 5 and operated b means of pull-rods 6 or otherwise and'usua lyrovided with returning-sprmga The typebars normally rest n contact at their type ends with a flexible ring or segment consieting, preferably, of an annulus or segment of lead or other yielding inelastic metal or substance 7, which may be faced with a softer inelastic substance 8a The latter may con sist of a strip such as sometimes used for beltlacing, some kinds of which are commonly soft, tough, and inelastic, and thestrip may bewound around the lead, so as to form a com 3 shows a modification.

plete casing therefor, as illustrated. The de vice may be supported in any suitable Way, preferably upon inturned fingers 9, formed at the lower edge of a thin stiif shcet-1netal ring or band 10, the latter being hung upon rods 11, attached to the top plate 5" or otherwise supported. In frontstrike machines the member 10 may be in the fornr of a segment and in some cases may be omitted. Y

The facing or swathing 8 prevents the softme'tal ring 7 from being cut by the type-bars and also minimizes the noise of the impacts. The bar 7 being flexible yields more or less at the impacts of the type-bars, and owing to this yielding movement some of the adjacent and opposite type-bars are jarred, thereby taking up much of the force of the blow and minimizing the reaction of the bar f2, so that it does not tend to throw the type-bar back with force, the tendency of the same to re bound being lessened, while owing to the inclastic character of the lead or other metal Y the force of the original blow of the typebar still further absorbed,particularly since the bar 7 is facedwith a soft inelastic material, so that the bar upon striking the basket may possibly drive sli htly past its normal position, but will. not rebound to the extent of causing it to clash with a subse uentl -0 er-.

e opera 10H ated type-bar. This enables t of the machine at high speed without danger from this source.

The curved frame or ring 10 is more substantial than the lead and protects the latter from inju ment of t e lead ring or segment. Prefer- It also prevents undue displace-- ably a narrow space is left at 12 between the ring orsegment 10 and the inner member, so as'to allow slight freedomof movement of the latten' During such movement there may be more or less friction between the sheathed lead member and the lingers or shelves 9, whereon it is supported, therebyfurther tending to absorb the force of .the type-bar blows.-

' At Fig 3 the lead ring or segment 7 is shown bare exceptffora facing 13 next to the typabars, consisting of inelastic belt-lacing orof any cushioningmaterial supported in any suitable manner.

. Variations may be resorted to within the 'sccpei-ofmy present improvements and portions' thereof may be usedwithout others.
